I know I will be probably the only one to think this, but if they do kiss after this scene, whether it's next chapter or not, I'll be disappointed.
The reason why is that we never got to see Mitsuki realizing her feelings for Aya. Nor even question her sexuality. But we got her internal monologue for other aspects of the story, so it's not like we are strangers to her internal process. For all we have been shown so far, while it's obvious that Aya have feeling for Mitsuki, the reverse could be false. Mitsuki could see Aya as just a really good friend and it wouldn't wrong how the story have been written so far. Of course, I know it's not the case, but for the sake of storytelling, it does bother me and break a bit the suspension of disbelief.
So in a way, if it were to happen now, it would feel fake for me. The chapter is great, and as much as I want to see them together, I do feel like it's missing some chapters of Mitsuki internal process to arrive to that result.
